Race track lid - mcmaster o-ring?

[htims05]

I've seen the mcmaster o-ring thread but I'm not finding anything about race track lid o-rings. Maybe it's the same o-ring but just a different oval diameter?

I picked up a 10 gallon Cornelius Company keg...and the lid o-ring is cracked and not holding...

Assuming it's the same for a 10 gallon keg as for a 5 gallon keg, that would be a -417 O-Ring, such as:

9452K218

ETA: BTW, I think most O-Rings are a lot cheaper if you buy them from oringsandmore.com rather than McMaster Carr. They are easy to cross because O-ing "dash" numbers (like -417) are standard.

Thanks for that tip- I actually have some -417 rings, the brand new one seems a little smaller in circumference than what's in there....granted I think that one has been in there for 20 years so likely stretched...I'll see if it holds.
